"I cannot work out from the photo which sort of skua you sent me - pomarine or Arctic. My ID book lists several clues, but I can not make them out in the picture...can you tell me which it was please?"

Suzanne

"The Skuas are Poms, notice the tail feathers are very visible in the vertical plane. This would not be so for an Arctic Skua. Size etc is difficult as there are only two of the same species in the shot so nothing to compare"

Terry

"Poms are also bulkier, more broad-winged and less falcon-like than the Arctic Skua..."

Pomarine Skua winter in tropical oceans and on the West African coast. In March they begin their journey to their Arctic tundra breeding grounds (They do not breed in the UK).

The Pomarine Skuas reach the North Atlantic in April, and the last week of April and first three weeks of May is their time of peak passage in Britain and Ireland. The sea-watching point Aird an Runair at Balranald in North Uist is one of the best places in the UK to see this spring passage from.

Smaller numbers of the birds are seen in August - November as they are en route to spend winter in the South.

 

The Pomarine Skua is probably a hybrid of a Great Skua and another Skua.
